I participated in this Patriotic Challenge last year and I believe it is an ongoing project with some of the members.

One member used to "host" a Virtual quilting day once a month and I enjoyed that, not sure if she still does that, but I've also seen lately where another member started a Virtual quilting weekend, where you work on projects & post pictures through out the day/weekend. It's kind of fun to see what everyone else is working on.
I'm also participating in the Block of the Month this year, and find that fun to see all the different colourways people use in their same pattern, you can jump in at any time & either catch up or just make the ones you like.
